A variety of surrogate modeling techniques has been utilized in high-frequency design over the last two decades. Yet, curse dimensionality still poses a serious challenge setting up reliable design-ready surrogates modern microwave components. The difficulty task is only aggravated by nonlinearity circuit responses. Consequently, constructing practically usable model, valid across extended ranges material, geometry, and operational parameters, far from easy. As matter fact, conventional are merely capable building models for structures featuring relatively small number designable parameters within reduced thereof. One possible way mitigating these obstacles may be employment recently proposed two-stage performance-driven approach. Therein, model domain narrowed down to section space where vectors adequate quality located, thereby permitting significantly reducing cost acquiring training data. Seeking even further reduction, this work introduces novel framework, which exploits problem-specific knowledge extracted responses achieve substantial cost-savings data acquisition. In our methodology, procedure targets response features instead complete characteristic locations response, such as relevant minima or maxima selected frequency bands. dependency coordinates said on dimensions considerably less nonlinear than observed characteristics, enables sizable reduction acquisition cost. Numerical validation involving three corroborates its remarkable efficiency, allows using handful samples.
